Recommendation: Monitor — no exploitation signal at the moment.
A flaw was found in GNU Coreutils. The sort utility's begfield() function is vulnerable to a heap buffer under-read. The program may access memory outside the allocated buffer if a user runs a crafted command using the traditional key format. A malicious input could lead to a crash or leak sensitive data.
